The plot is similar to the 1959 Audie Murphy movie "No Name On The Bullet". A notorious gunman (Paul Langton) rides into town, making everyone nervous, since they believe he's been hired to kill one of them. I think Murphy was better cast in the original movie, given his innocent, all American, bland handsomeness. Langton does well, not radiating any menace. The gunman in both the movie and this episode are congenial enough that each could've given up his career and settled down in town. Both actually make friends in the town. Both have a romantic involvement with a woman in the town. Given that the episode was only 1/2 hour, not much emphasis is given to the subplot of the original movie where many of the leading citizens have a guilty secret in which they something which would motivate someone to hire a gunman to kill them. This episode should have been a full hour long, to give some of the townspeople a backstory where they'd done dirt to someone. Imagine if Miss Kitty or the Doc had an ugly episode in their past! As is, the only interesting plot point is finding out who the gunman's target is.
